Convert Map to JSON object in Javascript

Question

So Ive got the following javascript which contains a key/value pair to map a nested path to a directory.

function createPaths(aliases, propName, path) {

Another approach. I'd be curious which has better performance but jsPerf is down :(.

var obj = {};

function createPaths(map, path, value)
{
	if(typeof path === "string") path = path.split(".");
	
	if(path.length == 1)
	{
		map[path[0]] = value;
		return;
	}
	else
	{
		if(!(path[0] in map)) map[path[0]] = {};
		return createPaths(map[path[0]], path.slice(1), value);
	}
}

createPaths(obj, 'paths.aliases.server.entry', 'src/test');
createPaths(obj, 'paths.aliases.dist.entry', 'dist/test');

console.log(obj);

Without recursion:

var obj = {};

function createPaths(map, path, value)
{
    var map = map;
    var path = path.split(".");
    for(var i = 0, numPath = path.length - 1; i < numPath; ++i)
    {
        if(!(path[i] in map)) map[path[i]] = {};
        map = map[path[i]];
    }
    map[path[i]] = value;
}

createPaths(obj, 'paths.aliases.server.entry', 'src/test');
createPaths(obj, 'paths.aliases.dist.entry', 'dist/test');
createPaths(obj, 'paths.aliases.dist.dingo', 'dist/test');
createPaths(obj, 'paths.bingo.dist.entry', 'dist/test');

console.log(obj);

var obj = {};

function createPaths(map, path, value)
{
    var map = map;
    var path = path.split(".");
    
    while(path.length > 1)
    {
        map = map[path[0]] = map[path.shift()] || {};
    }
    
    map[path.shift()] = value;
  
}

createPaths(obj, 'paths.aliases.server.entry', 'src/test');
createPaths(obj, 'paths.aliases.dist.entry', 'dist/test');
createPaths(obj, 'paths.aliases.dist.dingo', 'dist/test');
createPaths(obj, 'paths.bingo.dist.entry', 'dist/test');

console.log(obj);
